Good day all,
There have been a few instances where we've wanted to check our external DNS servers from various external networks, so we've utilized the existing looking glass tools provided by many of you. However, it's a very manual process, given that all LG's I've found say no automating/scripting. If we want to check from a couple dozen sites around the world, it's a lot of clicking and typing and collecting. If we wanted to create an tool that our NOC could use to verify our services, we would need something we could script. Ideally, we'd be able to run this constantly to do health checks on our services, but one step at a time.
A happy customer report for http://www.whatsmydns.net/ not scriptable as such, but very useful, and free into the bargain. I use it to check our GeoIP DNS is responding as expected. Matthew
